I've taken a bottle of vodka to my eye before. I blame the Kevin and Perry movie (eyeball Paul).
It really does get you drunk very quickly indeed. However, I'd say this is now very passe and they're behind the trend, I did this years and years ago. What noobs.
A few years ago, there was a guy in galvesron that had throat cancer, and he was such a raging alcoholic that he made his wife give him vodka enemas everyday. Dude eventually died of alcohol poisoning instead of the cancer.
